Technodrain Polyamide | Corrosion-Resistant Drainage

A corrosion-resistant black finish that maintains its appearance

One of the key advantages of the Technodrain Evo 100 Polyamide Grate and Channel system is that its corrosion resistance also supports its long-term appearance.

The Polyamide grate has a contemporary black finish and, because the material is inherently resistant to corrosion, it will not rust or change colour as a result of corrosion over time.

This is an important distinction in demanding environments. Rather than relying on a painted or coated metal surface to achieve its black appearance, the Technodrain grate is manufactured from high-performance Polyamide. Its corrosion resistance is an inherent property of the material.

This makes the black grate particularly well suited to highly visible drainage installations where both performance and appearance matter, including:

Swimming pools and aquatic centres;
Recreation and leisure facilities;
Beachfront developments;
Marinas and waterfront areas;
Coastal public spaces;
Resorts and hotels; and
Contemporary commercial and industrial projects.

The black finish provides a clean, discreet appearance that can integrate effectively with dark paving, landscaping and contemporary architectural finishes, while the material’s resistance to salt, chlorine and harsh cleaning agents makes it particularly suited to corrosive environments.

Designed for corrosive and chemically aggressive environments

The principal benefit of the Technodrain Evo 100 Polyamide is its ability to perform in environments where corrosion is an ongoing concern.

The Polyamide grate is impervious to rust and resistant to salt, chlorine and harsh cleaning agents. This makes it a compelling drainage solution for projects where conventional materials may be subjected to persistent moisture or aggressive environmental conditions.

In coastal and maritime environments, that can mean ongoing exposure to salt-laden air, sea spray and saltwater.

Around swimming pools and aquatic facilities, drainage may be regularly exposed to chlorinated water, cleaning products and continuously wet conditions.

Rather than attempting to protect the grate from these conditions with a surface treatment, Technodrain Evo 100 uses a material that is inherently resistant to corrosion.

Corrosion resistance without compromising strength

Choosing a lightweight, corrosion-resistant material doesn’t mean compromising on load performance.

The Technodrain Evo 100 Polyamide grate and channel have been load tested to 250kN under EN124’s C250 classification, equivalent to AS3996:2019 Class D.

This combination of corrosion resistance and strength makes the system suitable for consideration across a broad range of commercial, public-space and infrastructure applications where both environmental exposure and load requirements need to be addressed.

The Polyamide grate also incorporates an anti-slip surface, adding another practical benefit for swimming pools, recreation facilities, promenades and other environments where surfaces are frequently wet.

Lightweight and easier to handle

Polyamide also provides a high strength-to-weight ratio.

A complete 1 metre Technodrain Evo 100 channel fitted with two 500mm Polyamide grates weighs only 4.8kg.

For contractors, this lower weight can simplify transportation, handling, positioning and installation, particularly across projects requiring long drainage runs or sites where access is restricted.

This gives Technodrain Evo 100 a useful combination of benefits: corrosion resistance, Class D-equivalent performance, low weight and a black finish designed to maintain its appearance over time.

For architects, engineers, contractors and asset owners working in coastal, maritime, aquatic and other corrosive environments, the result is a channel drainage solution designed around both long-term performance and practical installation.
